Application November 16, 1944, Serial No. 563,726 Claims. (01. 5 2s4) Mypresent invention, in its broad aspect, has to do with improvements inair-cooling and conditioning means, and heating means for infants cabs,cribs and mattresses. Itis common knowledge that overheating of a babyis the occasion for much discomfort and illness, especially since a veryyoung child spends so much of the time in a cab, crib or bed, or upon amattress. An uncomfortable and overheated baby is not only an annoyanceto the mother, but the occasion of endless labor. The same may be saidof a .baby who is not Warm enough. My present invention is designed toprovide an air-cooling and conditioning means, which may be regulatedand adjusted, and which will not induce drafts, and

' which may be turned on and off at will. I also provide means forheating the mattress to prevent the baby from becoming chilled or coldin cold weather. While my device is especially designed for a cab, itmay be used with a crib, bed or the like.

Other and equally important objects and advantages of my inventionare(1) to provide a device which may be easily regulated and adjusted;(2) to provide means for properly distributing the cooling effectwithout drafts; (3) to provide a novel, useful and practical mattressconstruction; and (4) to provide a useful and practical heating device.i

Still further objects and advantages will be apparent from the followingdescription and drawings, but it is to be understood that changes inform, material, size, shape, construction and arrangement of parts maybe made without departingfrom my broad inventive concept or the scope ofthe appended claims.

In the drawings wherein I have illustrated a preferred form of myinvention- Figure 1 is a top plan view partly broken away toshowinterior parts;

Figure 2 is 'a sectional side elevation through the cab, partly brokenaway;

Figure 3 is a transverse section on the line 3-3 of Figure 1;

Figure 4 is a transverse section on the line 4-4 of Figure 1, and

Figure 5 is a plan view of the bottom supporting frame.

In the drawings wherein like characters of reference are used todesignate like or similar parts throughout the several views- Thenumeral I designates a part of a baby cab of suitable construction andwhich has sides 2, a front 3, a back 4 and a bottom 5' which is inclineddownwardly from the sides and front and back toward the center where thesame has a circular flanged opening 6 covered with wire screening 1.Mounted in the opening between the flanged part 6 is a motor 8. Themotor support is designated 9 and a battery [0 is mounted on the floorin the circuit H with the motor and a push button switch I2 at theback-of the cab. The motor drives a fan [3.

A mattress l4 having a bottom l5, ends l6, sides [1, and a top I8 issupported in the cab, and has at its bottom a strong wire frame l9 andlongitudinal supporting members 20 and trans verse supporting members2|. The transverse supporting members are in spaced pairs on which areseated telescoping hollow tubes 22 which are oval in cross-section andwhich extend upwardly to the top of the mattress and have flanges 23 and24 and their upper and lower edges respectively. About each tube is aspring 25 which presses against the flanges. The tubes are arranged inspaced pairs adjacent the sides and ends, thus providing a part of themattress medially and longitudinally and medially and transversely inwhich is a hollow rubber tubing member 26 in the nature of a cross withside legs 21 and longitudinal legs 28the center being over the fan l3 asshown in Figure 1. The tubing member is designed to be filled with hotwater or warm water through a capped filler mouth 29. A suitable fillerof cotton or the like 30 extends about the tubes 22 and rubber tubingmember 26 and beneath the supporting members 20 and 2|. The edges of themattress are rolled over and outwardly to form extensions as at 3I-seeFigures 3 and 4-to,prevent rising drafts about the edges of themattress, and beneath these extensions are openings covered bysuperposed vented plates 32 to regulate passage of air through and inthe mattress, since by sliding the outer plate 33 with reference to theinner plate 34 the size of the openings 35 may be regulated. The

cold, or warm or hot water, and the baby is at all outer plate isslidably held in a flanged frame 36 and has handles 31, A screen 38 isprovided back of the plates as shown in Figure 3. By "these means, airis forced upwardly through and into the mattressby turning on the fanl3, or the mattress is warmed by filling the member 26 with the cab hasa downwardly inclined bottom with the fan located at the lowermostpoint, means for cutting the fan on and ofi, and the fan located belowthe mattress.

3. The invention as defined in claim 1, wherein there are multipletubular members arranged in pairs, and wherein the fluid containingmember is in the form, 0! a cross with the spaced pairs arranged betweenthe arms thereof.

4. The invention as defined in claim 1 wherein the fluid containingmember isoval in cross section and formed substantially like a crosswith lateral and longitudinal arms, and has a capped filler opening.

5. An air conditioning and cooling and heatin device for babiescomprising a. mattress having a supporting frame carrying inner springs,tubular members formed with telescoping sections within the springs andforming channels for air circulation, a tubular member between saidsectional tubular channels to receive hot or cold fluid, an aircirculating means, the mattress having overhanging lateral edges, andadjustable valve means below the edges to control ventilation within themattress.
